Wavefront analysis uses a special device to precisely measure the unique irregularities and variations in the cornea. This analysis has been compared to taking a fingerprint of the eye.
With your chin resting on the device, you will be asked to stare past what is called a target light. A sensor will measure the irregularities in the wavefront pattern of the light reflecting from your cornea.
Wavefront measuring devices create a precise map of the cornea. It is very detailed and records subtle distortions in your cornea. Using the information from this map, your ophthalmologist can select the intraocular lens used in your surgery to correct for some of these measured distortions, giving you clearer vision than would be possible with conventional lenses. Wavefront analysis is not covered by OHIP.
